A used 4L60E transmission is a great option for those who want to save money. The used transmission is a better option than a rebuilt or remanufactured unit. You may save money, but the costs are higher. A used transmission must be removed and shipped to a salvage yard for inspection, which may cost extra. The added cost of a used transmission may be more than that of a remanufactured or rebuilt one.
The 4L60-E transmission has the same power transmitting core as its predecessors. The only difference is the throttle position sensor, which is tied to the engine's powertrain computer. The higher horsepower of a 4L60E is tied to its size. Likewise, the 4L80E is more expensive than a 4L60E, so it may not be as suitable for a powerful engine. Therefore, it's a good idea to check the torque converter before installing a new transmission.
